MX5 Miata Intercooled SUPERCHARGER Racer Kit---NO ELECTRONICS : 2006-2012

Formerly known as the "Cosworth MX5 Supercharger" kit and now sold without the Cosworth name. This RACER kit gives you all the hardware without the calibration and cuts over $1000 from the original price so the enthusiast can pick their own calibration choices!

This bolt-on MX5 Miata Supercharger system features a state of the art 4th generation Eaton MP62 rotating group housed in an integral inlet manifold. This Miata Supercharger kit was designed as a compact, flexible supercharger system for increased power with original equipment quietness and reliability without adversely affecting fuel economy. The Eaton MP62 has proven itself in a number of OE applications. The bolt-on MX5 Miata Supercharger system features an efficient air to water intercooler, upgraded fuel system and complete installation hardware. A high flow air box cover and a revised accessory drive arrangement complete the major components list.

(Not CARB exempt which means not legal for California highways). See our Mazda Talk forum for many more pictures of the installation on our own 2007 MX5 Miata and additional information.

INSTALLATION NOTES Install of the factory oil cooler recommended and sold separately on this same website. We also recommend that hard driving or racing customers consider an upgraded clutch such as our ACT clutches. Owners of AUTO trans need a standard automatic transmission oil cooling kit from their local auto parts store.

BRIAN'S APPLICATION NOTES: New Racer kit is $1000 cheaper and does NOT include calibration. The VERY FIRST PRODUCTION SUPERCHARGER kit for this generation MX5 was installed here at Good-Win Racing. Other retailers have jumped in the game but nobody can match our experience with racing these supercharger kits weekend after weekend. Bottom line is that this kit gets an otherwise stock MX5 to about 200 hp at the wheels (up from only about 130 hp at the wheels). To get much beyond 200 HP you need a full exhaust and our RoadsterSport Header (see our Dyno Results of 266 HP at the wheels with our 2007 MX5). You will need either our MOTOEAST kit or XEDE to control fuel and timing...and we recommend all installations be dyno tunned for appropriate Air/Fuel ratios. All Track users should add our water injection kit (any street user who raises the boost level beyond what is in the kit should also take this suggestion for our water injection).
